it is 5 small phillips head screws. you will need a stubby screwdriver for the back ones and if you are unlucky you'll have to pull the heater housing to get to the one in the very back. the heater housing is also only held on by 3 or 4 bolts but they go through the firewall and you might have to take them off from the engine side of the firewall.
